PERMANET BED FOR RAILWAYS.

Specification of Letters Patent.

Patented Dee. 19, 1916.

Application filed May 25,1916. Serial No. 99,840.

'following is a specification.

This invention relates to permanent beds for railways, one of its objects being to provide a reinforced concrete bed or foundation having novel means for engaging and supporting the rails, said rails being4 detachably secured in place by simple and 'efficient means provided for that purpose.

W ith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

1n the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a perspective view of a portion of a permanent bed such as constitutes the present invention, said bed being also shown in section. Fig. 2 is a vertical transverse section through the bed and the rails thereon. Fig. 3 is a transverse section through a portion of the bed at a point midway between two of the cross ties.

Referring to the figures by characters of reference 1 designates a foundation formed of broken stone placed in the bottom of an excavation and above drain tiles 2 which are extended longitudinally along the bottom of the excavation. The central portion of the foundation is preferably thicker than the side portions, as shown at 3 and the en-V tire foundation isv covered with a layer of concrete, indicated at 4 and in which are embedded cross ties 5. rllhese ties are preferably anchored by having their ends offsetV as shown at 6, each end being preferably split to form separate tongues one of which is extended upwardly while the other is extended downwardly within the concrete.

The ties 5 are exposed at the bottoms of longitudinal channels 7 formed in the concrete and in which are snugly seated longitudinal supports or stringers 8 preferably formed of metal. These stringers are of any desired length and the ends thereof are secured together by cross pins extending transversely therethrough, as indicated at 9, it being understood that each of these stringers is` provided at one end with a tongue l0 while its other end has a recess 11 so that the tongues of the stringers will be extended downwardly therethrough andv screwedinto the straps, as shown particularly in Fig. 2.

rlhe rails 13 are held against longitudinal or upward displacement relative to the stringers by means of bolts 15 which extend through openings in the base Hanges of the rails 13 and engagethe stringers 8.

The cross ties or straps 5 can be arranged .any desired distances apart and, if desired, the stringers can be further held at points between the cross tiesor straps by embedding studs 16 in the concrete 4f so that they will project upwardly into the channels 7 Where these studs are provided, recesses 17 are formed in the bottoms of the stringers 8 for the reception of the studs.

t will be obvious that after a road bed as herein described has once been constructed, it will require practically no attention thereafter and should the rails become worn or broken they can be easily removed by detaching the bolts 15, whereupon other rails can be placed in position within the channels 12.

What is claimed is:-

1. A permanent bed for railways, including a stone base of greater thickness at the center than at its sides, a concrete covering upon the base and having parallel channels, tie straps embedded within the concreteand flush with the bottoms of the channels, stringers resting upon said tie straps and fttingsnugly within the channels, the upper faces of the stringers being flush with the top surface of the concrete, there Ybeing longitudinal channels within the stringers, means extending through Vthe Ystringers for detachably securing them to the tie straps, and means for detachably securing rails within the channels in the stringers.

2. A permanent bed for railways, including `a stone base thicker at the Center than at the sides, drain tiles disposed under the side portions of the base, a concrete covering upon the base and having parallel Channels, tie straps embedded within the concrete and flush with the bottoms of the channels, stringers snugly seated within the channels, the stringers in each channel abutting and interftting at their ends7 coupling pins-extending transversely through the interfitting ends of the stringers, said stringers having longitudinal channels in their upper faces, means extending through the stringers for detachably securing them to the tie straps, and means for detachably securing rails in the channels in the stringers.

In testimony that I Claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
